Go to a dark area, for example wayrest sewers and move the black slider from 1 to 5 until the least amount of acceptable brightness in the dungeon, or whatever is comfortable (4 is default) Turn off reshade -> Navigate to Video -> Gamma adjustment -> Click on 'Calibration' and stop the slider exactly on the point the left most logo disappears into black then turn on reshade again, the calibration must be done while reshade is off. Set a toggle key in the settings tab for turning preset on and off, default is delete Select the ESO_Redefined preset and arrange the effects in order if Reshade doesn't automatically arrange it (Very important)
Run the game and press Shift+F2 ( Shift+Fn+F2 on laptops) to open Reshade menu, if it doesn't open press Home button Download and extract ESO_Redefined.rar into SteamLibrary\steamapps\common\Zenimax Online\The Elder Scrolls Online\game\client where eso64.exe is located
